STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

Not applicable.

BACKGROUND 1. The Field of the Present Disclosure

The present disclosure relates generally to surgical systems and methods of facilitating the efficiency and accuracy of implanting surgical prostheses using mixed reality and 3D spacial mapping devices.

2. Description of Related Art

In traditional implant surgeries, for example, knee replacements, a surgeon will utilize a metal jig which is used as a drilling or cutting guide to make the necessary corresponding cuts and holes in the bone of the knee to facilitate placement and attachment of the implant to the bone. However, these metal jigs must be stocked in a variety of different sizes to accommodate different needs and sizes of patients, accordingly, significant stocks of metal jigs must be stored and sterilize. Additionally, use of these metal jigs include inherent inaccuracies as the surgeons fix the metal jigs with respect to the corresponding bone during use as a drill or cutting guide.

The femoral implant and tibial implant are designed to be surgically implanted into the distal end of the femur and the proximal end of the tibia, respectively. The femoral implant is further designed to cooperate with the tibial implant in simulating the articulating motion of an anatomical knee joint.

These femoral and tibial implants, in combination with ligaments and muscles, attempt to duplicate natural knee motion as well as absorb and control forces generated during the range of flexion. In some instances however, it may be necessary to replace or modify an existing femoral and/or tibial implant. Such replacements are generally referred to as revision implants.

To prepare a femur and tibia for such a knee replacement and form an engagement with femoral and tibial implants, the femur and tibia bones must be cut in very specific and precise ways and at very specific and precise angles and locations, so that the prepared bone will properly engage with and be secured to the corresponding implants. In order to make these cuts properly, a surgeon traditionally uses a jig, or surgical cutting guide as known to those skilled in the field, which can be removably attached or secured to the bone, such that slots, or guides, in the jig facilitate the precise cuts necessary to secure the corresponding implants.

The phrase “jig” as used herein, shall thus refer broadly to a surgical cutting guide, that may be configured and arranged to be fixed or attached to a bone, or secured adjacent to a bone or other tissue to be cut by a surgeon and identify a relative location, angle and/or cutting plane that a surgeon should cut or drill on the adjacent bone or tissue, as known in the art. A jig may include predetermined slots and/or cutting surfaces to identify where a surgeon should cut the adjacent bone or tissue, wherein such cuts may correspond to a shape of a surgical implant that may be attached to the cut bone or tissue. A “cutting surface” may refer to a guide edge for guiding the path of a cutting instrument.

Conventional jigs are typically made of a metal alloy and, due to the precise tolerances at which these jigs must be machined, are quite expensive, ranging as high as $40,000-$50,000 in some cases. These metal jigs must also be stored and reused, which adds additional cost and space resources. Additionally, jigs of various sizes must be kept on had to accommodate patients of different sizes and needs.

Therefore, there is a need for a system that can utilize a less expensive jig, such as a plastic jig, that could be made easily and on demand, while maintaining the required tolerances and enable the same accuracy in use in a surgical procedure.

In other conventional embodiments, holographic jigs, also referred to a virtual jigs, have been used to enable a surgeon to visualize the positioning and proper sizing of a jig to a bone. However, in use, when the surgeon attempts to superimpose a physical jig over the virtual jig to attach it to a bone to make the required bone cuts, the physical jig will impair the view of the virtual or holographic jig, making it difficult to utilize the holographic jig to accurately place the physical jig.

Accordingly, there is a need for a system and method of utilizing a virtual or holographic jig or surgical instrument that could facilitate increased accuracy and precision of required or desired bone cuts.

The phrase “virtual jig” or “holographic jig” as used herein, shall thus refer broadly to any visualization or visual rendering or projection representing an actual physical jig, having all, or mostly all, of the same visual characteristics of the physical jig, including size and shape, as known in the art.

The features and advantages of the present disclosure will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by the practice of the present disclosure without undue experimentation. The features and advantages of the present disclosure may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims.

Referring to FIG. 1 , in a disclosed embodiment a mixed or augmented system 100, which can be used to produce, or display, a desired mixed or augmented reality instrument, such as a virtual jig or cutting guide in a display to a surgeon or user, or stated another way, that is visible and manipulatable by a surgeon or user. The mixed or augmented reality system 100 may also enable a user to activate or deactivate, in full or in part, the virtual instrument or instruments, making a virtual instrument appear or disappear, as desired in a mixed reality assisted surgery, for example.

The mixed or augmented reality system 100 may include a mixed or augmented reality headset 102 which may include a transparent or mostly transparent viewer 104 which can be suspended or positioned in front of a user's eyes. The headset 102 may include a headband 106 attached to the viewer 104, which may be used to secure the headset 102 to a user's head 108, thereby securing the viewer 104 in place in front of the user's eyes.

The transparent viewer 104 may be configured to project, or otherwise make viewable, on an interior surface of the viewer 104, a holographic image or images, such as a virtual device, for example, a virtual cutting guide, which may be positionally manipulated by the user, surgeon, third party or remote system, such as a remote computer system. The headset 102 may be configured to view holographic images or, alternatively, the holographic images may be turned off and the user wearing the headset 102 may be able to view the surrounding environment through the transparent viewer 104, unobstructed. As such, a user, such as a surgeon for example, can wear the mixed or augmented reality headset 102 and then can choose to activate a holographic image to aide in facilitating a surgical procedure and then shut off the holographic image in order to perform the surgical procedure un-obscured, visually.

One embodiment of the disclosed headset 102 may be a product created and manufactured by Microsoft, known as the HoloLens® mixed or augmented reality system, or any suitable mixed or augmented reality system for generating virtual images viewable by a user or surgeon. Headset 102 may be a conventional “off the shelf” product with a built-in platform that enables all of the features described herein with respect to the headset 102. Furthermore, the headset 102, such as a Microsoft HoloLens product, can be loaded or preloaded with all desired or required virtual instruments, including virtual jigs or surgical cutting guides, virtual drill bits, and/or a virtual target which can identify relative locations of a plurality of holes to be drilled by a surgeon to facilitate the fastening of a jig or other device onto a desired bone at the proper desired location, and any other desired virtual instruments or holograms. The Microsoft HoloLens product and its capabilities and features, or any suitable mixed or augmented reality system such as is described herein with respect to the headset 102, are known to those skilled in the art.

The mixed reality system 100 may also include a computer or computer system 200 having enabling software to communicate with the headset 102, by both receiving information from the headset 102 and transmitting data and images to the headset 102. It is therefore to be understood, by way of the circuit diagram and dashed lines shown in FIG. 1 , that headset 102 is electronically connected to the computer system 200 and a 3D spatial mapping camera 300. The 3D spatial mapping camera 300 is electronically connected to the headset 102 and the computer system 200, as shown in the circuit diagram and dashed lines shown in FIG. 1 . While the 3D spatial mapping camera 300 may be electronically connected to the headset 102, the 3D spatial mapping camera 300 may be separate from and not mechanically connected to the headset 102.

The mixed reality system 100 may also include a 3D spatial mapping camera 300. One embodiment of the disclosed spatial mapping camera 300 may be a product created and manufactured by Microsoft, known as the Azure Kinect®, or any suitable 3D spatial mapping camera capable of continuous 3D mapping and transition corresponding 3D images, such as bones, anatomy, or other desired 3D objects. The spatial mapping camera 300 may be a conventional “off the shelf” product with a built-in platform that enables all of the features described herein with respect to the spatial mapping camera 200. Furthermore, the spatial mapping camera 200, such as a Microsoft Azure Kinect product, can be loaded or preloaded with all necessary software to enable wireless communication between the spatial mapping camera 300 and the computer system 200 and/or the headset 102. The Microsoft Azure Kinect product and its capabilities and features, or any suitable 3D spatial mapping camera such as is described herein with respect to the spatial mapping camera 300, are known to those skilled in the art.

The spatial mapping camera 300 may include sensor software development kits for low-level sensor and device access, body tracking software development kits for tracking bodies or objects in 3D, and speech cognitive services software development kits for enabling microphone access and cloud-based or wireless speech services.

Additionally, the spatial mapping camera 300 may include the following features: depth camera access and mode control (a passive IR mode, plus wide and narrow field-of-view depth modes); RGB camera access and control (for example, exposure and white balance); a motion sensor (gyroscope and accelerometer) access; synchronized depth-RGB camera streaming with configurable delay between cameras; external device synchronization control with configurable delay offset between devices; camera frame meta-data access for image resolution, timestamp, etc.; and device calibration data access.

The spatial mapping camera 300 may also include software development kits that enable a viewer tool to monitor device data streams and configure different modes; a sensor recording tool and playback reader API that uses the Matroska container format, as known to those of ordinary skill in the field; a library and runtime to track bodies in 3D when used with the spatial mapping camera 300; contains an anatomically correct skeleton for each partial or full body; provides a unique identity for each body; can track bodies over time; and speech services, such as, speech-to-text, speech translation and text-to-speech.

The headset 102, computer system 200 and spatial mapping camera 300, may be programmed and configured to enable a surgeon 107 to see and manipulate a virtual, or holographic target or jig, with respect a patient's bone 400, anatomical, or any other desired location, which may receive a surgical implant. The headset 102, computer system 200 and spatial mapping camera 300 may communicate with one another via a local network connection, wifi, bluetooth, or any other known wireless communication signal.

Specifically, the spatial mapping camera 300, that may be programed to communicate with the computer system 200 having enabling software, may utilize such enabling software to map the bone 400 and or jig 500, or other desired anatomy, to help identify the proper location for fastening a jig, or other device, to the bone 400, prior to cutting the knee.

The spatial mapping camera 300 differs from traditional imaging, such as an MRI, CT scan, x-ray or the like, in many ways. For example, the spacial mapping camera 300 may be mounted, fixedly or moveably, in an operating room, thus giving the most up-to-date mapping information possible. The spatial mapping camera 300 may also continuously map the surface and 3D contours of the bone 400 to provide the surgeon 107 with realtime feedback and information to make the proper drill holes, cuts, or other preparations on the bone 400, before, during, and/or after any given procedure.

The mixed reality system 100 may also include an alignment jig 500 that can be secured to the exposed bone 400, or other desired anatomy. The jig 500 may includes a first marker 502 which may be attached to the jig 500 at a fixed location on the bone 400. The first marker 502 may include a scannable, optical or visual label 404, such as a QR code. The jig 500 may also include a second marker 510 that may be moveable with respect to the jig 500 and the bone 400. The second marker 510 may also include a scannable, optical or visual label 412, such as a QR code.

The mixed reality system 100 may also include a surgical tool 600, such as a drill for example, that may also include a scannable label 602, such as a QR code, which can be scanned by the headset 102 and or spatial mapping camera 300, which may include data related to the jig 500, surgical procedure, and/or the corresponding patient. This data may be transmitted and processed by the computer system 200, which may then prompt or identify to the surgeon 107, via the headset 102 where, and at what angle, to position the tool 600 to drill, cut, or otherwise prepare the bone 400, at the proper location on the bone 400.

In another embodiment, as shown in FIG. 2 , the headset 102 and the spatial mapping camera 300 may utilize a physical calibration tool 700 to calibrate and align 3D coordinates with the 3D contours of the exposed bone 400 or anatomy. The calibration tool 700 may include a specially designed calibration pattern 702 than may be scanned by the headset 102 and/or the spatial mapping camera 300, which can then send the corresponding calibration data to the computer system 200 which can then use the calibration data to provide accurate coordinates to the headset 102 to identify where to drill, cut, or otherwise prepare the bone 400.

In a further embodiment, as shown in FIG. 3 , the mixed reality system 100 may also include a pin guide 800 that may also include a scannable label 802, such as a QR code, which can be scanned by the headset 102, which may then prompt or identify to the surgeon 107 where, and at what angle, to position the pin guide 800 to perform a desired procedure, at the proper location on the bone 400. The pin guide 800 may also include a guide sleeve 804 which can provide a directional guide to receive and orient a pin (not shown) to be placed by the surgeon during a procedure. the surgeon to drill, cut, or otherwise prepare the bone 400.

Using the mixed reality system 100, a surgeon or user may perform a surgical procedure by first exposing the bone 400, or other desired anatomy. The spatial mapping camera 300 may then continuously 3D spatially map the exposed bone 400, and send the corresponding mapping information to the computer system 200. In alternative embodiments multiple spatial mapping cameras 300 may be used in unison, to provide more accurate and expansive imaging.

The surgeon may then attach the jig 500 to the exposed bone 400, at a predetermined or desired location. The spatial mapping camera 300 may spatially map the jig 500 and the exposed bone 400, to map the surface of the exposed bone and relative location of the jig 500.

The surgeon may then utilize the headset 102 or spatial mapping camera 300 to scan the fixed scannable label 504 of the first marker 502 and send the corresponding information to the computer system 200. The computer system 200 may then utilize data from the 3D spatial mapping camera 300 and the scannable label 502 of the first marker 502 to determine the orientation of the moveable second marker 510 and send the data to the headset 100.

As shown in FIG. 4 , the headset 102 may generate a holographic image 900, or visualization, viewable by the surgeon on the viewer 104, such that the surgeon can maintain a real-world view of the bone 400 and simultaneously view the holographic image 900. The holographic image 900 may include a realtime rendering of the exposed bone 400 and a realtime rendering of the jig 500. The headset 102 can then scan the scannable label 512 of the second marker 510 and identify the proper or required position of the second marker 510, relative to the bone 400. This identified position of the second marker 510 may be viewed by the surgeon in holographic image 900. The surgeon can then manipulate the rendering of the second marker 510 in the holographic image 900, until the proper position is set and determined.

Once the proper position of the second marker 510 is set in the holographic image 900 the surgeon can use the headset 102 to lock the holographic image 900 in place. Then the surgeon can manipulate the actual physical second marker 510 to substantially match the positioning of the set rendering of the second marker 510. A target 514 located on the second marker 510 may provide the surgeon with the substantially exact location to drill a required hole, or place a pin, with respect to the exposed bone 400, such that the surgeon can manipulate the location of the jig with respect to the bone 400, to substantially match the location of the virtual jig, or holographic image 900, with respect to a virtual bone.

The headset 102 may help facilitate the proper orientation of the second marker 510, and corresponding target 514, by illuminating the target 514 or by providing a colored symbol, either of which may include a color, such as red, that may change colors, such as changing from red to green, when the target is ultimately moved into the proper position, by operation of a microprocessor (not shown) contained within headset 102 or computer system 200, said processor being programed as known to those skilled in the art of programming to trigger a change of color when the target is moved into the proper position.

As shown in FIGS. 5 and 6 , the headset 102 may then scan the scannable label 602 of tool 600 or scannable label 802 of pin guide 800 and identify the location and angle of the tool 600 or pin guide 800, to make the required drill hole, or pin insertion. The headset 102 may help facilitate the proper orientation of the tool 600 or pin guide 800, by providing a colored symbol 750, such as red, that may change colors, such as green, when the tool 600 or pin guide 800 are ultimately moved into the proper position. The surgeon may then use the properly oriented tool 600 or pin guide 800 to perform the corresponding procedure or preparation of the bone 400. A cutting jig (not shown) may then be attached to the bone 400 at the prepared position.

A surgical jig is conventionally, and may be, a surgical tool that may be used to help a surgeon make predetermined and accurate cuts of a desired bone to facilitate attachment of a surgical implant. A jig may have one or a series of slots located at specific predetermined locations and at specific predetermined angles, with respect to a body of the jig, such that when the jig is attached to a bone surface, the surgeon can make precise and accurate cuts, using the jig as a guide, without the need of additional measurements. Once the desired cuts of the bone have been made using the jig as a guide, the jig may be removed from the bone and the surgical implant may be properly secured to the bone which has now been accurately cut to receive the implant.

Due to the accuracy of the disclosed method and system, the jig 500 may be made of plastic, metal, polyamide, or any other desired material. Manufacturing the jig 500 out of a plastic or polyamide material, or other relatively inexpensive material, may allow the jig 500 to be disposable, while still maintaining the precision and accuracy of traditional metal jigs. The jig 500 may also be manufactured using a 3D printer, which can further reduce the cost of manufacturing and storage of jigs, since 3D printed jigs could be made on demand, customized to the size and shape required by individual patients and users. The physical jig 500 may also be manufactured using any other known technique for forming a physical jig.
